Study on Properties of Cooling in Capillary Tube Air-Conditioning System

Based on elaborating the characteristics of capillary tube air-conditioning system, especially investigated the heat transfer property of this system cooling in summer, and establishes a two-dimensional mathematical model of steady-state heat transfer. In this paper, the Matlab program programmed by a micro-body heat balance method focuses the impact on the ceiling temperature field and the cooling performance of the factors such as temperature of supply water and return water and the pipe space. Then compared the computing results with the experimental results, it turns out that the numerical solutions of the heat transfer per unit area calculated by the model are in good agreement with the measured values, which provides the technical support for the design and promotion of the capillary tube air-conditioning system.
